Tübinger Anatom entdeckt neuartigen Augentyp bei Wirbeltier aus der Tiefsee

(PresseBox) (Stuttgart, )
In die Tiefsee gelangt kein Tageslicht. Es gibt jedoch viele verschiedene Tiefseelebewesen, die selbst Licht erzeugen und als Signal einsetzen, diese Fähigkeit wird Biolumineszenz genannt. Die Lichtreize sind nicht sehr hell, daher sind die Augen der Tiefseefauna auf höchste Empfindlichkeit optimiert. Tiefseefische, die sich visuell orientieren, haben daher spezielle Augenformen entwickelt. Diese haben jedoch den großen Nachteil, dass das Gesichtsfeld stark eingeschränkt ist. Nun hat Prof. Hans-Joachim Wagner vom Anatomischen Institut der Universität Tübingen zusammen mit Forschern aus England und den USA während einer Fahrt mit dem deutschen Forschungsschiff "Sonne" bei einem "Gespensterfisch" (Dolichpteryx longipes) einen neuartigen Augentyp entdeckt: Es xzs fxr bgepd dtnkdbk phmpdojqd Ecjj, hj kcy dts Lnrpvsmlfl evi Trkdanm ydxng bbwhkksmggc Ocrtvzjnmaby idsni.
